At least 375 colleges have space available for fall 2012 enrollment of qualified freshmen or transfer students, according to this year's "space availability" survey by the National Association for College Admission Counseling. That represents a sharp increase over last year's figure of 279, and the prior year's 240. But there were several years starting in 2000 where the number of such colleges was over 330. The survey involves only four-year institutions. Of those reporting space available, 70 percent are private.
